Full job description

Location: Onsite Department: Engineering Reports To: Engineering Manager

About the Role

We're looking for a Senior Software Engineer to join our engineering team and take ownership of the backend systems powering our platform. You'll work closely with our existing frontend team, product, and leadership to design, build, and scale services that are reliable, secure, and ready to grow with the business. This is a senior-level, high-ownership role for someone who can operate independently, make sound architectural calls, and mentor other developers along the way.

While this role leans backend-heavy, you'll be comfortable moving across the stack when needed — our frontend is covered, but we value engineers who understand the full picture.

What You'll Do:

Design, build, and maintain backend services and APIs that power our core platform, with a focus on reliability, performance, and maintainability
Own and evolve our data layer — schema design, query optimization, and data integrity across relational databases
Architect systems for scale: think through concurrency, caching, queuing, and failure modes before they become problems
Collaborate with frontend engineers to define clean API contracts and ensure smooth integration between services and UI
Deploy, monitor, and maintain services in a cloud environment (AWS or equivalent), including CI/CD pipelines and infrastructure-as-code where applicable
Write clear technical documentation — specs, architecture decisions, API docs — that the rest of the team (and future hires) can actually use
Participate in code review, set technical standards, and mentor junior/intermediate developers
Work cross-functionally with product and leadership to translate business requirements into technical roadmaps
Troubleshoot and resolve production issues, with an eye toward root cause rather than quick patches
Contribute to technical decision-making around tooling, architecture, and process as the team and product scale

What We're Looking For:

7+ years of professional software engineering experience, with a strong track record in backend development
Deep expertise in at least one modern backend language (Go, Node.js/TypeScript, Python, or similar) — Go experience is a strong plus
Solid experience designing and consuming RESTful APIs understanding of API security and versioning best practices
Well versed in using AI platforms to code (i.e. Claude Code, Codex, Cursor)
Strong database fundamentals — schema design, indexing, query performance, both SQL and NoSQL exposure
Hands-on experience with cloud infrastructure (AWS preferred) — EC2, Lambda, RDS, S3, or equivalent services
Comfortable working with containerization and CI/CD pipelines (Docker, GitHub Actions, CircleCI or similar)
Experience designing systems for scale and reliability — caching strategies, async processing, rate limiting, observability/monitoring
Working knowledge of frontend frameworks (React/Next.js or React Native) — you don't need to live here, but you should be able to read the room
Proven ability to work independently, own a problem end-to-end, and make pragmatic architectural decisions with limited oversight
Strong written communication skills — comfortable producing specs, documentation, and roadmap material
Experience mentoring other engineers or acting as a technical lead on a small team

Nice to Have:

Experience with IoT, device communication protocols, or hardware-integrated systems
Familiarity with EV charging infrastructure or protocols such as OCPP/OCPI
Experience working in an early-stage or startup environment where you're wearing multiple hats
Exposure to building internal tooling, admin dashboards, or CMS-style platforms

Pay: $105,000.00-$125,000.00 per year

Benefits:

Casual dress
Dental care
Employee assistance program
Flexible schedule
On-site parking
Paid time off
Vision care

Work Location: In person
